Now, according to the two aspects of Gödoel's theorem, proof of the consistency of arithmetic cannot be represented within the system (there is no endoconsistency), and the system necessarily comes up against true statements that are nevertheless not demonstrable, are undecidable (there is no exoconsistency, or the consistent system cannot be complete).

The concept just always is its consistency in its variations: “the concept is defined by its consistency, its endoconsistency and exoconsistency, but it has no reference; it is self-referential.”

The exoconsistency between concepts depends on their being able to inhabit the same plane.

However, just as it was impossible to understand the concept of solidarity in Deleuze and Guattari without the concept of 'exoconsistency' (that bridged the concrete machines between different abstract machines), so it is impossible to understand the concept of solidarity in Zapatismo without also understanding the concept of puentes or 'bridges' that connect the concrete actions and consequences of different political events.
